ELECTRIC SWITCH.

SPECIFICATION forming part of Letters'Patent No. 761,133, dated May 31, T904.

l Application filed September 30, 1902. Serial No. 125,434. (No model.)

T0 (ir/ZZ whom, it nfl/tty concer-n:

Be it known that I, HENRY PRICE BALL, a citizen of the United States, residing Vat New York, county of New York, VState of New Yorlr, have invented certain new and useful Improvements in Electric Switches, of which the following is a specification.

My invention relates to oil-switches; and it consists in the construction of the switch and the mechanism employed for operating the switch and also to the support for the oil-well of the switch. v The object of my invention is to simplify the construction of such switches andto provide a convenient and simple means for supporting the oil-well of the switch on the back of the switchboard.

The accompanying drawings will serve'V to illustrate my invention, in which'- Figures 1 and 2 are side elevations of the switch mechanism, also showing Avertical sections through the switchboard, supportingplate, and oil-well. These views, respectively,

show the switch .inthe closed and open positions and illustrate different forms of support for the oil-well. Fig. 3 is a view of the actuating mechanism looking from the right of Figs. 1 or 2. Fig. 4 is an enlarged detail of a portion of the support for the oil-well shown in Fig. 1.

Similar letters and numerals indicate like parts throughout the several figures.

In the drawings, A indicates a switchboard. Mounted on the back of the switchboard is a bracket B. This bracket may be constructed as shown in Fig.- 1 or as shown in Fig. 2. Mounted inthe bracket B is a support O for the oil-well D. In Fig. l the support O is shown as attached to and forming a part of the oil-well D. This support has two arms E F. The arm E is carried backward and then upward as a pin portion G, which is introduced in a shaped slot H in theupper arm I of the bracket B. This slot is given a peculiar shape, as shown in Fig. 4, to permit of the angular movement of the pin portion G. The lower armF of the support C is provided with a dovetail end J, which takes in a corresponding dovetail slot K in the lower arm L of the bracket B. By lifting the oil-well upward until the dovetail end J leaves the dovetail part K the well may be tilted and detached from the bracket B.

It will be observed that the shaped slot H permits the angular movement or' the pi portion G of the support.

The support O' in Fig. 2 is pivoted in the bracket B and has its left-hand end M located in a socket N in the bottom of the oilwell D. When it is desired to' remove the oil-well, it islifted from the support O, which latter is swung out of the way.

Y In the construction shown in Fig. 1, as well as that shown in Fig. 2, it will be noticed that the oil-well D or Dl is supported entirely independent of the other portions of the switch.

Projecting from the back of the switchboard is the supporting-plate O. The bottom of this support is provided with the ianges P, which receivethe top of the oil-well D or D. Mounted upon the support O are the insulators Q, and carried in' these insulators are the conv ductors R. .On kthe lower end of these conductors are the spring-.plates S.

Mounted to reciprocate in an opening in the top of the support O is a rod T, on the end of which is a bridge-piece U, formed of conducting material and carrying on its outer ends the spring-contacts V, which are adapted to cooperate with the spring-contacts S on the end of the conductors R. Mounted upon the upper side of the support O is a vertical guide W for the reciprocating rod T.

To make and break contact in the switch from a distance, I make use of the magnets 5 5', which are mounted in a bracket 6 on the front of the switchboard. Within these magnets are the cores 7 8. To these cores are connected a band 9, which passes over a bandwheel l0,r mounted on shaft 11, which has its bearings in the bracket 6. f

Mounted on the shaft 11 is a crank-arm 12, which is pivotally connected to the bent lever 13. The opposite end of the lever is pivotally` connected to the short arm 14 of a bellcrank 15, which is pivoted at 16 at the top of the support O. The opposite arm 17 of the bell-crank is pivotally connected to a link 18, also pivotally connected at its upper end to the reciprocating rod T.

The operation of this portion of the device will be readily understood. When a current is sent through the magnet 5', its core 8 is attracted and the bandwheel 10 and crankarm 12 are rotated to the right to the position shown in Fig. 1, thereby reciprocating the rod T vertically and causing the bridgepiece U to lap the contacts S of the conductors R. Conversely, when a current is sent through magnet 5 its core 7 is attracted and the band-wheel and crank-arm 12 are rotated to the left to the position shown in Fig. 2, thereby reciprocating the rod T vertically and causing the bridge-piece U to break contact with the contacts S of the conductors R.

I do not limit myself to the mechanism described for effecting the motion of the Vertically-acting bridge-piece U. Other electrical or mechanical devices may be employed.

Having thus described my invention, I claim- 1. In an electric switch, the combination of aswitchboard, a bracket-support projecting from said switchboard, switch mechanism carried by said support, an oil-well mounted under said support, and means for supporting the oil-well independently of the support.

2. In an electric switch, the combination of a switchboard, a bracket-support projecting from said switchboard, switch mechanism carried by said support, and an oil-well detachably and independently supported immediately beneath said bracket-support.

3. In an electric switch, the combination oi' a horizontal plate, switch mechanism carried by said plate, comprising in part switch-contacts and a vertically-reciprocating bridgepiece, an oil-well in which the switch-contacts and bridge-piece are immersed, and means for supporting the oil-well independently of the horizontal plate.

4. In an electric switch, the combination of a horizontal plate, switch mechanism carried thereby, comprising in part switch-contacts and a reciprocating bridge-piece, electromagnetic means for reciprocating the bridge-piece, an oil-well, and means for supporting the oilwell independently of the supporting-plate.
